We have 2 CRV'S, after a long history with Honda, I've come to understand that the MM is an algorithm, most based on averages, cycles, time, miles & temperature. It has nothing that relates to or measures actual oil condition. I'm probably overly pro-active, but I actually do Blackstone Labs UOA's that DO measure oil condition. Given the CRV's 1.5t's proclivity to oil dilution and it's difficulty reaching operating temperature in cold weather, I generally follow a 4-5k change schedule. MM is usually at 30-40% at that point. My last UOA showed the oil I had been using, Mobil1 0W-20 AFE/M110A filters had 1.3% dilution and had thinned out of grade after 4100 miles of mixed driving. I've recently changed to Mobil1 0W-20 EP and will probably go to Royal Purple filters, also considering Castrol Edge EP as well, but will continue shorter change intervals and do the UOA's. Oil is cheap, engines are expensive and sooner is better than later. I trust Honda engineering but I don't see the percentages in running lubricants to their limits in a vehicle I expect to have for some years.
